Lead, cadmium, nickel, manganese, cobalt and copper contents of some play dough, face and finger paint samples were determined by using a new solid phase extraction method which has been developed by using multi-walled carbon nanotube with patent blue (V) sodium salt to selectively separate and preconcentrate these metal ions. Flame atomic absorption spectrometry was used to determine the metal ions. Analytical parameters affecting the complex formation and solid phase extraction performance such as pH, the amount of ligand and volume of sample solution were investigated. The recoveries of the studied metal ions were not affected by the foreign ions. Analytes were recovered quantitatively at pH 5.5 and with a nitric acid of 2 mol L-1 as eluent. Analysis of a certified reference material was performed to validate the method before applying it to determine the metal ions in the real samples. Detection limits were found to be as Pb(II): 7.71 pg L-1, Cu(II): 1.43 pg L-1, Cd(III): 0.21 mu g L-1, Mn(II): 0.47 mu g L-1, Ni(II): 3.52 mu g L-land Co(II): 1.96 pg L-1.
